Nang pawhin i chau reng em? Thawhrimna nei lo ang maiin i inhria em? I doctor chuan thisen report a en a, "iron tlakchhamna" emaw "anemia" emaw a ti mai thei. Hei hi kan rama mi tam takin harsatna an neih chu a ni. Chuvangin, kan taksaa he thil pawimawh tak iron an tih hi tuin nge control tih i hria em? Chumi atan chuan "boss" tak tak a awm. Amah hi Hepcidin an ti a . He hming hi i hre lo pawh a ni thei. Mahse kan taksa hriselna atana hna a thawh hi thil tenawm tak a ni lo. Vawiin hian kan taksaa he "iron boss" chungchang hi han sawi ila.
A awlsam zawngin, he Hepcidin hi tu nge ni?
Hepcidin hi kan thin (liver) atanga siam, thisena chhuak hormone a ni. Hormone hi kan taksaa hnathawh zawng zawng thununtu palai ang mai a ni. Chuvangin hepcidin an tih messenger hna ber chu kan taksain iron a hman dan control hi a ni. A dik tak chuan taksain thir engzat nge a mamawh tih te, a khawlkhawm tur zat te, chu thir chu engtikah nge a hman a ngai tih te chu amah hi a ni. Chuvangin mi thenkhat chuan hepcidin hi "Master Iron Regulator" an ti thin.
Chuti a nih chuan engvangin nge thir hi kan tan a pawimawh em em?
Kan taksa pum puia oxygen phur thei delivery service a awm ang tih han ngaihtuah teh. Chu delivery service lirthei chu thisen sen (red blood cells) te hi an ni . Chu lirthei chhunga oxygen dahkhawmtu chu hemoglobin an tih protein a ni . Chuvangin he hemoglobin siam nan hian iron hi thil pawimawh tak a ni. Iron tel lo chuan hemoglobin siam theih a ni lo. Tichuan thisen sen (red blood cells) te hian oxygen an phur thei tawh lo. Chutah chuan kan chau a, thawk harsatna kan nei thin.
Chu mai ni lovin, kan taksa peng leh thinlunga oxygen petu protein myoglobin siam nan pawh iron a ngai a ni.
A awlsam zawngin, thir hi kan taksa cell-te nunna petu oxygen phurtu system thinlung a ni. Chuvangin he iron level hi balance taka vawn reng a pawimawh hle. Iron a tlem chuan iron-deficiency anemia ang chi natna a lo awm thin. Iron a tam lutuk chuan kan taksa tan toxic a lo ni thei a, taksa peng hrang hrang a tichhe thei bawk. Chu balance vawn reng chu hepcidin hnathawh ber a ni.
Engtin nge hepcidin hian he iron hi a control theih?
Hei hi thil mak tak a ni. Kan ei leh in (sa, sangha, thlai, nut) atang hian iron kan hmu thin. Mahse mineral dang ang lo takin kan taksa hian iron tam lutuk paih chhuah dan a nei lo. Entirnan, sodium (salt) kan neih tam lutuk chuan zunah a chhuak ang. Mahse iron hi chutiang chuan a chhuak awlsam lo.
Chuvangin, a hnua hman tur thir tam lutuk dahkhawmna a kawk a ni. He iron hi kan ruhroah a awm ber a , .Spleen leh liver ah te .
Hei hi hepcidin hi a rawn inrawlhna hmun a ni. Hepcidin hian he iron management-ah hian kawng pawimawh pathum hmangin a inrawlh a:
1. Chaw atanga iron lakluh dan a thunun: Kan chaw ei chu kan ril te tak teah a luh chuan chuta cell te chuan thisenah iron an hip lut thin. Hepcidin hian thisenah iron engzat nge a chhuah tih leh engzat nge a dahkhawm tih a hril a ni.
2. Thisen sen hlui atanga iron recycle: Kan thisen sen dam chhung chu ni 120 vel a ni. Chu hun a tawp chuan macrophages , thisen var chi khat (taksa ‘cleaning crew’ ang chi) chuan heng thisen sen hlui te hi a tichhia a ni. Mahse an tih chuan an chhunga thir hlu tak chu an man a, an dah khawm thin. Chuvangin, hepcidin hian he iron dahkhawm hi thisen sen thar lo awm tawhte hnenah pek let leh tur nge, hun engemaw chen dahkhawmna hmuna dah tur nge tih chu a rel a ni.
3. Liver ang hmuna Iron dahkhawmte a chhuah dan a control: Hepcidin hi taksain a mamawh huna thisenah iron dahkhawm ( hepatocytes ) leh small intestine cells ( enterocytes )-a dah luh leh chhuah loh tur thu a hrilh thin a ni.
Engtin chiah nge hei hian hna a thawh?
Hei hi hrethiam tur chuan mi dang kan hriat a ngai a ni. Chu mi chu protein pakhat ferroportin an tih a ni . Cell chhunga thir dahna hmun ang maiin han ngaihtuah teh. Ferroportin chu chu storage room atanga "gate that lets iron out" a ni. Thir thisen chhunga a luh theih nan he kawngkhar hi hawn a ngai a ni.
Hepcidin hian a tih chu he gate hi a control a ni.
- Taksa chhunga hepcidin level a san chuan hepcidin hian ferroportin an tih gate a binding a, a khar thin . Tichuan, cell chhunga thir chu thisenah a lut thei lo. Iron absorption a tlahniam.
- Taksa chhunga hepcidin level a tlahniam chuan , ferroportin gate a tikhawlo lo. Chuvangin gate chu a inhawng ta a ni . Cell chhunga thir chu awlsam takin thisenah a lut a. Iron absorption a tipung.
Hepcidin level inthlak danglam chhan hi engte nge ni?
Kan taksa hi a fing hle. Engtik lai pawhin an mamawh angin hepcidin level an tisang emaw, an tihhniam emaw thin. Hei hi thil pawimawh tak tak engemaw zat a awm a.
